Manifolds

In automotive engineering, an intake manifold or
inlet manifold is a part of an engine that supplies the fuel/air
mixture to the cylinders. An exhaust manifold or header collects
the exhaust gases from multiple cylinders into one pipe. The
word "manifold" literally means "hand shaped", which arises from
the "fingers" leading to each cylinder.
Due to the suction effect of the downward movement of the
pistons in a reciprocating piston engine, a partial vacuum
(lower than atmospheric pressure) exists in the intake manifold.
If the engine has a throttle valve (i.e. in spark ignition
rather than diesel engines) this manifold vacuum can be
substantial, and can be used as a source of automobile ancillary
power to drive auxiliary systems: (ignition advance, power
assisted brakes, cruise control, windscreen wipers, power
windows, ventilation system valves, etc). This vacuum can also
be used to 'suck' any piston blow-by gases from the engine's
crankcase. This is known as a closed crankcase ventilation or
positive crankcase ventilation (PCV) system. This way the gases
are burned with the fuel/air mixture.
The intake manifold is located between the carburetor and the
cylinder head. On multi point injected engines, the intake
manifold holds the fuel injectors.
Exhaust manifolds are generally and traditionally simple cast
iron units which collect engine exhaust and deliver it to the
exhaust pipe. However, when greater performance is required,
this restrictive tube is often replaced with individual headers
which are tuned for low restriction and improved performance.
There are two types of headers. Collector style headers use
pipes that merge into a collector, and can be utilized with
mufflers. Collector headers can be used for the street or for a
race car. Zoomie headers have no collectors, and are used
exclusively on race cars. Headers have been widely available
from aftermarket sources for decades, and some manufacturers
have begun using them as original equipment. The Honda J30A2
engine does away with exhaust manifolds altogether, using an
integral engine block passage to route gases directly to the
catalytic converter.

HKS GT2510

Optimized for maximum power
from 7,000 to 10,000 RPM, the Victor X manifold
is designed for turbo and all-motor
applications. Engineered for high performance
and race set-ups, this manifold has four
additional bosses for nitrous or added fuel
injectors. Match with the Edelbrock 65mm
throttle body for maximum power. Also available
with four extra machined injector bosses and a
matching machined extruded aluminum fuel rail.
Injectors and wiring sold separately.
